A further object of the invention is -.to

provide a key controlled means whereby .the operator can cause the carriage to return any selected distance in a line and at the same time cause the platen to rotate.

A still further object is to provide a key controlled'means whereby the operator can rotate the platen without returning the carriage. p

With the above and other objects in view which will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter more .particularly described and later pointed out in the appended claims.

16 and 16 are a'pair of hangers secured to the carriage, which hangers move therewith and have their extendin lower ends connected by a cross bar 16 t e bar being provided with a space scale 17.

18 is a horizontally disposed rod carried permanently by the extremities of the hangers. The rear side of this rod or that farthest from the frame is formed with a more or less right angled groove 18 running lengthwise of the rod. A series of similar equal spaced teeth 19 extend into the groove, the teeth being V-shaped in vertical cross section and having the apex of the V centered in the angle of the groove. It will here be noticed that the scale has a series of equal spaced marks thereon, which marks correspond inv number to the number of spaces which the carriage travels when going from one end of the machine to the other. There is a tooth 19 for every mark, less one, on the scale. The rod is also provided on the inner side or that nearest the frame with a second L-shaped groove 20 which runs lengthwise thereof. Similar equal spaced teeth 21 froject into this latter groove, the number 0 teethin this instance being the same as the number of teeth on the rearside of the bar. The teeth 21 form a rack on the rod and I wish it to be under- I stood that hereinafter when I refer tothe rack I mean the teeth.on the inner side of this rod. The purpose of these teeth will be later apparent.

22 is a stop selecting lever carried by a sleeve 22' rotatably mounted on' the rod. The sleeve carries an inwardly projecting V.

shaped dog '23 designed to enter the spaces between the teeth 19 when the said lever is swung downwardly and toclear from between the teeth and enter the upper portion of the groove when said lever 1s swung upf wardl 22 1s a stop plate secured to thesleeve and designed to arrest the lever when turned upwardly, said plate engaging with the bar 16 I 24 is a spring carried by a. pin 24' screwed into the sleeve. The spring is arranged to force thelever downwardly at'all times. It

trally at the back of the machine and permanently secured to the frame. The bracket is constructed to present opposing horizontally disposed top and bottom guides 25" and 25 the top guide being supplied with a cross T-shaped groove 26 which receives slidably the releasing bar 26 fitted at one end with an upwardly directed striking tab 26 27,- 28 and 29 are three finger keys car- "ried by the bars30, 32 and 31 respectively, 'WhlCh bars are mounted to swing on a cross rod 33 extending across the machine frame. These keys are located preferably at the ends of the present spacing bar indicated at 34 in "Fig. 30f the drawings. However I do not wish to be limited to any location as they can be put in at any suitable place. The bars 30 and 32 are turned inwardly and connect respectively with further key bars 30' and 32 while the key bar 31 is connected to a further key bar 31' pivotally mounted on the rod 33 and located between the bars 30 and 32. The bars 30, 31 and 32 are pivoted on the rod 33 as are also the forward ends of the bars 30' and 32. The bars 30, 31

and 32 extend backwardly through a suitable suspending bracket 35 located centrally at the b ack of the machine frame and have their rearmost ends entering open bottom cross slots 30*, 31 and 32 formed in a head 36 fitted with an extending shank 36' which screw-threads .into the lower end of a tubular contact tip suspending rod 37 This rod passes upwardly slidably through a C11- cular opening 37 formed in the guide 25 and also slidably through a circular opening' 37 appearing in the top guide 25' a short distance above which it terminates. The releasing bar 26 is fitted with a more or less elongated circular opening 26 which permits the rod to pass through it. opening is elongated to permit the releasing rod to be shifted'endwise slightly for a purpose later explained. The upper end of the rod is supphed with an insulating bushing 38, which. receives a contact tip 39 hereinafter termed the lower contact tip.

39 is a nut threaded on the contact tip and bearing on the bushing. 0

40 is a wire connected with the contact tip and passing downwardly within the rod LMa The enlargement 41 is located atall timesabove the key bar- 32'. The upper end of the bar passesfirst-slidably through the bracket the bar 26 respectively, these slots communieating with the openings 37 and 26 hereinbefore mentioned. The bar is no'tched to form a catch 44 whereby the bar can be suspended in the upper: position, when desired, by-the catch engaging with. the body of the-releasing bar, which bar it will be noticed .is held normally in a set position by a fiatspring 45 carried by'the' main bracket 25. The arrangement-is such that when the parts are in the position shown in Fig. 8 of the drawings the bar 41 is held in its upper position and cannot release until the tab 26 is struck in a direction which will carry the slot 43 away from the bar, this motion being permitted by the elongated opening 26 already referred to. It will here also be noticed that owing to the peculiar connection of the bar 41 with the head, the head is held up at all times with the bar and drops with it, although it is possible for the head to be raised independently of the bar as the enlarged end 41' thereof can slide freely in the grooves 41 46 is a spiral spring having the lower end thereof permanently secured to the guide 25 and the upper end thereof connected to a hook. 46' extending from the rod 37. This spring tends normally to hold the rod in its lower position, and consequently has a constant tendency to hold the head 36, the rod 41 andattachments in their respective lower positions.

47 is a second bracket secured permanently to the bracket 25 and carrying slidably a vertically disposed sleeve 47' in which 'I have mounted a bushing 47 material which carries a top contact tip 48. A spiral spring 49 is inserted between the under face of the bracket 4-7 and the sleeve, which sprin mally in its owermost position. The upper contact tip48 is centered directly above thecontact tip 39 hereinbefore referred to.

50 is a locking rod having the lower end thereof forked and spanning the bar 31',

the forks carrying a roller 50' which op- I erates in a suitable slot 5i formed inthe bar. The upper endof the rod'is received slidably within an openin 52 locatedin the guide 25' and the end 0 said rod is contracted and alined directly with the opening between the teeth 21 of the rack formed on .the inner side of the rod 18. In the natural position of the key the rod is down, that is, away from the rack. 53 representsan electric motor of which 54 isthe drive shaft 55 and 56 are the terminals. J

of insulating tends to hold the sleeve nor- 29 controlling this rod, b ing arranged to engage with the jointed 57 represents a number of batteries or other source of electro-motive force, which batteries-are connected by a wire 58 with the terminal 55 of the motor and by a wire 59 with the lower contact tip 39, this connecti'on being made through the rod 40, thewire 59 passing to the rod through an insulating ferrule60 located in the side of the rod 37. The terminal 56 of the motor is connected by a wire 61 with the contact tip 48, the wire being connected to the contact tip by lock -mediately to the inner side ofthe ratchet wheel 11", it being understood that the ratchet-wheel is free to rotate with the spindle, the plate remaining stationary. The plate is supplied with a projecting arm 66 which passes to the side of the ratchet wheel and carries a bell crank 67 pivotally mounted on a pin 67 "extending from the face of the arm. One end of the bell crank is connected to a cable 67 which has the opposing end thereof wound around and secured to the pulley 64:. The opposite end of the bell crank is jointed and is arranged so that when the said bell crank is turned, the jointed end thereof engages with one of the ratchet teeth of the wheel and upon the continued movement of the bell crank turns the wheel a certain set number of teeth, the joint in the bell crank being provided to permit the same to free from the teeth or drop back after the carriage has been returned.

67 is a stationary anchoring arm secured by a cross pin 67 to the pin 67 The arm is received normally within a slot 67 provided in the bell crank, as is clearly apparent in Fig. 13 of the drawings.

67 is a spiral spring having one end secured to the extending end of the arm 67 and the other end fastened to the jointed end of the bell crank. The spring is supplied to return the bell crank to the initial position after it has been actuated and released by the deenergization of the motor, as later explained. The distance which the bell crank can swing on the pin 67' is controlled by the lever 68 pivotally secured by pivot pins 69 to a swivel 70 rotatably mounted in the arm 66, which arm it will be noticed is notched away to permit the lever to lie normally flush with the upper face thereof.

The inner end of the lever is supplied with a. pair of stop pins 68 and 68 the pin 68' by depressing the outer end of said lever the lever to hold the inner end thereof with the pin 68 in one or other of the holes 71 according to the adjustment made. The holes 71 are spaced so that the bell crank can turn the ratchet wheel one, two or three teeth as the case may be, depending on whether the pin 68 is in the first, second or third opening 71. turning carries with it the platen so that I am enabled by this construction to turn the platen to cause single, double or triple spacing in writing. For convenience in operating, the armor lever can be supplied with suitable means to indicate whether the lever is set at the single, double or triple space position.

72 is a grooved collar flxed on the spindle ll between the knob and the face of the ratchet wheel.

' 73 is a spring bar having the lower end thereof entirely spanning the collar and received within the groove and the upper end thereof passing through a suitable slot 73 located in an overhanging arm carried by the plate 65. The upper end of the spring 73 is forkedand bears against across pin 74 carried by a l'ockinglever 7 suitablymounted on the arm 65'.

v 76 is a ball normally engaging 'with" the teeth of the ratchet wheel and carried by a more or less hemispherical socket 77 permanently secured to the body of the spring bar 73. When the lever is in the upright position the ball is engaged with the teeth of the ratchet wheel but upon one swinging the lever downwardly he withdraws the ball from the teeth as the pins 74 force the spring bar backwardly. in the slot 7 3'. The

bar is locked in this position bv the lever.

In order to better understand my invention I will now describe the manner in which the parts operate. At the outset the operator sets the lever 68 so that the machine will write single, double or triple spacing as he may select, the setting being accomplished and inserting the in 68 in one or-other of the openings 71.- e next sets the stop-selecting lever 22 with the dog 23 between any selected pair of teeth 19 .on the rod 18, thereby limiting the distance which the carriage travels on the .return shift. This locking lever actually controls the margin ap: pearing on the left hand side of the typewriting sheet.

to return the carriage he depresses the key 28. This key operates the bars 32 and 32 in a manner such that the notched bar 41 is The ratchet wheel in The carriage is primarllyshifted to the initial position and after the line has. been written and the operator wishes parts are so gaged that when the notched baris so locked, the contact tip 39 is en-- gaged with the tip 48. Immediately this occurs, the circuit is closed through the motor, with the result that it starts rotating and in so doing .draws on the cable 67 2 which winds on the pulley. During the initial pull of the cable the bell crank is swung against the action of the spring 67 until it engages with the pin 68 of thelever 68, which motion rotates the platen the selected spacing, owing to the bell crank catching the teeth of the ratchet wheel. After this has occurred, the cable continues winding and as the bell crank cannot turn farther the cable draws and returns the carriage until the lever 22 hits the striking tab 26 of the releasing bar. This shifts the bar back against the spring 45 and releases the notchedbar from the bar 26.- The notched bar, head and rod 37 immediately drop to the original position, this being facilitated by the action of the spring 46. When the rod drops, the contact through the contact tips is broken and the circuit is opened. Immediately the circuit is broken, the motor is deenergized and the spring 67 operates to return the bell I crank to the initial position. The cable, during this operation, is wound off' the pulley 64, which, due to the deenergizing of the will operate, first to turn the platen and then 'to shift the carriage.

Immediately the selected lateral position ofthe carriage is reached, the key 27 is released and the head immediately withdrawing, owing to the action of the spring 46, immediately breaks the contact between the tips and stops the movement of the carriage. It will be seen in this connection that the head operates freeof the notched bar. The enlarged end 41 thereof during this operation simply slides freely in the grooves 41 provided. If the operator wishes at any time during the writing operation. toturn the platen, he simply depresses the key 29 which operates through the bars 31 and 31 to raise the looking rod 50 and also'the head 36. As the locking rod goes up, the upper end thereof engages with the rack on the inner side of the rod 18 and in so doing prevents the rod and consequently the carnage from moving. Further, the head 36 in shifting makes contact between the contact pieces 39 and 48 icence I p the result that the platen is turned by s drawing on the bell crank. limmethe key'in question is released, the

:ns and breaks the contact and the (l passes away from the rack. it is here explained that it is necessary to have the locking rod lock the carriage before the circuit is closed through the contact tips.
